SPECIFICATION formingpart of Letters Patent No. 450,381, dated April 14, 1891.

Application filed August 6, 1889. Renewed July 10, 1890. Serial No 358,267. (No model.) Patented in England July 22, 1,889,

No. 11,672, and in Germany July 31, 1889,1T0. 52,499.

To all whom it may concern.-

Be it known that 1, JOHN SMITH, a subject.

of the Queen of Great Britain, residing at Elms Road, Burton-on-Trent, in the county of Stafford, England, have invented new and useful Improvements in Apparatus for \Vithdrawing Bungs or Shives from Casks, (for which I have obtained a patent in Great Britain, No. 11,672, bearing date July 22, 1889, and in Germany, No. 52,499, bearing date July 31, 1889,) of which the following is a specification.

The object of this invention is to facilitate the withdrawal of barrel bungs or shives without injury to the staves or bung-bushes of the casks.

In the accompanying drawings, Figure 1 represents longitudinal section of an apparatus for withdrawing bungs or shives from casks constructed according to my invention. Fig. 2 represents side elevation of same. Fig. 3 represents plan of same. Fig. 4 repre sents extractor detached from the apparatus.

According to this invention the apparatus consists of an approximately circular portion a to encircle the bung or shive. On one side of the portion a is a projecting piece I), forming a bearing, on which works a cam-lever c. On the opposite side of the portion a is a divided handle d, having a lever e pivoted to the end thereof at f. This lever carries the extractor 9/, consisting of the knife h, connected by the circular portion 2' to a square or other suitably-shaped neck j, which neck terminates in a head 7;. The lever e haspivoted to it atl the cam-lever c. \Vhen the ex'- tractorg is inserted in the lever e, a loose piece m is inserted to fill up the superfluous space and kept in position by any suitable means, such as a pin 72-, a spring 0 serving to keep the extractor pressed against the portion 1) of the lever e.

To withdraw a shive or bung from a cask, the apparatus is placed over the shive, the extractor g driven through the shive in the direction of the grain, the apparatus turned about a quarter of revolution on the circular portion 71 of the extractor g as a pivot, and the cam-lever c struck down in the direction of the arrow by the mallet or other implement with which the extractor g is driven. The shive will thus be extracted without the workman having to change or lay down his tools.

I would remark in conclusion that I do not limit myself to the precise details of the apparatus or knife shown in the drawings.

What I claim. as my invention and desire to secure by Letters Patent, is-

In an apparatus for withdrawing bungs or shives from casks, the combination of the approximately circular portion a, having at one side a projection b and having at its opposite side a projection d, to which is pivoted the lever e, through which lever passes the extractor g, with the cam-lever c pivoted to the lever e and bearing upon the projection 11,2111

substantially as described.
